Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an example of reducing the amount of exhaust gas from a vacuum cleaner that contains bad odors and fine dust emitted into a room, and improving cleaning performance.

FIG. 1 is a partial cross-sectional view showing the configuration of a conventional vacuum cleaner. In the figure, +11 is the intake port, +21#'i
The extension pipe that is the intake passage, 13) is the main body, and (4) is the filter.

(51 is an electric blower, (6) is an exhaust port.

The air sucked in from the intake mountain along with the dust from the electric blower (5) reaches the main body (3) through the extension gf+21.

The air from which dust has been removed by passing through the filter (41) is discharged through the exhaust port (6).

This exhaust air contains fine dust and bad odors, and has a harmful and visible moving spear, and it is wasteful and undesirable to release it into a busy room.

This invention was made to eliminate the drawbacks of conventional vacuum cleaners, and by discharging the exhaust air from a vacuum cleaner through an exhaust outlet near the intake port, the amount of general exhaust air released into the room can be reduced. The purpose is to reduce and improve the scavenging (2) nB force.

FIG. 2 shows an embodiment of the invention -f! It is an iVS cross-sectional view. +41. +51 is exactly the same as the conventional kimono. (7) is an exhaust outlet provided so that the outer button exhaust flows into the intake port along the entire circumference of the intake mountain.

(2) is an extension pipe consisting of an exhaust passage +91 and an intake passage aOj.

In the vacuum cleaner configured as described above.

The exhaust air from which dust has been removed by the filter is the exhaust passage (9)
(through) Exhaust outlet (7) Air blower 1 For example, blows up dust and dust found in urine. This dust-laden exhaust air is sucked back into the vacuum cleaner body through the air intake mountain.

The amount of exhaust gas released into the room will be reduced.

In the above embodiment, the exhaust outlet was provided along the entire circumference of the suction ridge, but the same effect can be expected even if the exhaust outlet is provided only on a part of the outer periphery of the intake port. FIG. 3 shows a case in which it is provided only at the front edge of the T-shaped intake port. FIG. 4 shows the case where the T-shaped intake port is provided only at the rear edge. FIG. 5 shows the case where it is provided only at the front and rear edge of the T-shaped intake port.

(3) It goes without saying that the same effect can be expected even if the air outlet is divided into two or more parts in the embodiments shown in Fig. 2, Fig. 3, Fig. 4, and Fig. 5 above. .

Furthermore, similar effects can be expected even if the exhaust outlet is placed inside the intake port (1). FIG. 6 shows a case where the exhaust air outlet O is located inside the intake port.

In the case of Figure V-6, the exhaust air can be blown to any one point, so for example, dust scattered in the corner of the S store can be blown away and sucked in again.

Further, in the above embodiment, the extension pipe (8) is a double pipe, but it goes without saying that the same effect can be expected even if the exhaust passage and the intake passage are composed of two separate pipes. .

Now, in this invention, the exhaust air after collecting dust is blown onto the area to be cleaned, and the head there is blown up and sucked in again, but the exhaust volume and intake volume are Because they are equal, if even a small amount of the surrounding air is sucked in, the dust will blow up and the exhaust air will not be able to be sucked in and will be released into the room.

In order to prevent this, the off-line diagram is a curved view of an extension pipe equipped with an exhaust outlet for collecting dust and discharging -S of the exhaust gas (4) directed toward the outlet. (9) is the exhaust passage, and tlol is the intake passage.

Reference numeral 1111 is an exhaust discharge port through which the amount of exhaust discharge can be adjusted wJ.

By discharging a part of the exhaust gas heading towards the exhaust outlet, the amount of air blown out at the intake port is also reduced and prevents the exhaust from escaping from the intake port. be able to.

As explained above, this EA is based on the method of blowing out the exhaust air near the intake port and sucking it in again.

This has the effect of improving the cleaning ability of the vacuum cleaner and reducing the total amount of harmful exhaust gas emitted into the room.

[Brief explanation of the drawing]

Figure 1 is a partial diagram showing a conventional vacuum cleaner. Figure 2 is a partial partial view showing an embodiment of the present invention. 3, 4, 5, and 6 are cross-sectional views of an air intake port showing other embodiments of the present invention, respectively. The off view is a sectional view of an extension tube showing another embodiment of the present invention. In the figure, the mountain is the intake port, (2) is the extension pipe, and (3) is the main body.
